Voice Cloning Best Practices

  • Use high-quality recordings (at least 44.1kHz sample rate) - Ensure minimal background noise - Avoid music or sound effects - Use consistent recording environment
  • Include varied sentence structures - Cover different emotions and tones - Include questions, statements, and exclamations - Avoid repetitive content
  • Minimum 3 files, maximum 10 files - Each file: 10-60 seconds - Total duration: At least 2 minutes - Supported formats: MP3, WAV, FLAC
Voice processing typically takes 10-15 minutes. You’ll receive a webhook notification when your voice is ready to use.
